3. Make certain that there is no slack in the deicer lead strap between the terminals and the clip.
This is important because it assures enough slack between the clip and the strap restrainer to allow for
proper feathering. A test should be conducted on each propeller deicing system to insure that deicer lead
straps are installed in such a manner that the propeller can be moved from full low pitch through the
feathering position without placing the straps in tension.
- NOTE -
Deicers should have a piece of gray plastic bonded to the air side
(shiny side) of the deicer strap as shown in Figure 30-22. The strap
restrainers should be positioned as shown in Figure 30-23 when the
propeller blades are in the full feather position.
4. If damage occurs to slip ring wire harness, rubber spacers or hose clamps, replaced damaged parts.
BALANCING.
To assure balance of the propeller assembly, the original balancing weights or their equivalents must be
reinstalled. The weights must be left in their original position on the propeller hub. The restrainer and
weights should not interfere with any part of the propeller assembly under any condition. If for any reason
balance weights were removed, reinstall safety wire on screws.
